Most cars would run out of oil between oil changes consuming 1 quart every 800 miles. That is why they have a "dip stick" to measure how much oil is in the engine.
You are courting a high repair bill if you don't check the level of your oil between changes.
When my kids first started driving, I showed them how to check the oil and told them they could drive the car without checking how much gas it had if they wanted to, but they had better not drive it without knowing how much oil it had.
You're missing the point. NO NEW CAR should burn all of its oil in less than 7,500 miles. Period. Thats a defect. That works out to at least two complete oil changes between regular oil changes. They know how to fix this problem and don't. Its about them cutting costs. Identify 5 new competitor vehicles that are supposed to burn that much oil, more than a quart in a thousand miles. You can't because its a defect.
